GitHub登录

import requests

session = requests.Session()    #实例化，维持会话
url_login = 'https://github.com/login'
    response = session.get(url_login)
    #通过正则获取token值
    authenticity_token = re.findall('name="authenticity_token" value="(.*?)" />',response.text)[0]
    print(authenticity_token)

当我们获取该参数后，即可以代入form-data中完成登录

附上全部代码

import requests
import re

session = requests.Session()    #实例化，维持会话

def token():   
    url_login = 'https://github.com/login'
    response = session.get(url_login)
    #通过正则获取token值
    authenticity_token = re.findall('name="authenticity_token" value="(.*?)" />',response.text)[0]
    return authenticity_token     #返回token值

def url_session(token):
    url = 'https://github.com/session'
    data = {
        'commit': 'Sign in',
        'utf8': '✓',
        'authenticity_token': token,     #authenticity_token参数
        'login': '输入账号',              #你的账号
        'password': '输入密码',          #你的密码

    }
    response = session.post(url,data=data)  #传入form-data表单
    return response.text   #返回源码

def save_github(response_text):  
    with open('github.html','w',encoding='utf-8') as fp:
        fp.write(response_text)

if __name__ == '__main__':
    token = token()   #获取authenticity_token参数
    response_text = url_session(token)    #获取网页源码
    save_github(response_text)    #把爬取到的源码保存为html格式
